To all whom it may concern:

Be it known that I, FRED R. KUNimL, a

citizen of the United States, and a resident of =Edgewood Park, in the county of Allegheny and State of Pennsylvania, have in-- vented a new and useful Improvement in Pivotal Connections, of which tliefollowing is a specification.

My invention relates to pivotal connections, and articularly to such connections are empoyed between fan notoriii and similar devices and supporting standards is a view, in side elevation, of a motor and its supporting standard which embody my'invention. Fig. 2 is a v1ew, part1ally in sec tion and part ally mend elevation, of the parts shown in Fig. 1. Fig. 3 is a pers'peetive View of certain of the parts of the pivotal connection between the motor. and the supporting standard, and FigQ-i is a' perspe'ctive view of the upper endof the supporting standard forth'e motor.

An electric motor-'1 (such, as thatconstituting the subject-matter of another application Serial No, 4:10221, filed by me of even date herewith) is supported by, and pivotally connected to, a drawn sheet metal tubular standard or base 2 the upper end ofwhich is rectangular in cross-section. The upper edges of two sides 3 and dot the rectangular end of the standard are rounded concentrically with apertures 5 therein, and

the other sides Sand 7 thereof are provided with slits 8 along .-.their edges I and are rounded at their upper ends to conform, in

shape, to the rounded edges of the sides 3 and 4. The sides 3 and at of the rectangular portion of the standard 2 are embraced by, and clamped between, the legs of two nested substantially U-shaped clips 9 and 10 that are riveted or otherwise secured to the motor 1,

the legs of the clip 10 comprising co1nparatively narrow necks 11 provided with eyes 12 at their outer ends. The clips 9 and 10 are pivotally connected to the" standard 2 by means of a bolt 13 having a wing nut 14 screw-threaded upon one end thereof, -'the for example,

said bolt being surrounded, between the legs of the clip 10, by a sleeve 15. Terminal con-' ductors 16, of the motor 1 extend 'downwardly into. the standard 2 through openings in the; bottom of the motor'fcasingand corresponding openings in the clips 9 and "'10, and -also through the space between the inwardly rounded ends of the sides 6 and. 7 of the standard 2. j

' It will be noted that, when 'pressure is applied to the parts of the'pivotal connection by means of drawing nut 14, the sides 3 and 4 of the standard 2 are securely clamped between the clips 9 and 10, and the legs of the clip 10 are clamped between the sides 3 and 4 of the standard 2 and the ends of .the sleeve 15, there" being thus provided a large number of surfaces upon which '1. The combination with a member having spaced sets of spaced projections, of another ,member] having projections interposed between and pivotally connected to the projections upon the aforesaid'member, and means for clamping together adjacentproj ections.

2. The combination with a member having spaced sets of spaced projections, of another member having projections interposed, between the projections upon the aforesaid member, a bolt pivotally connecting the pro- =jectionsi1pon one member to those upon the other, and a sleeve surrdunding the bolt between the said sets of projections.

3. The combination with a substantially rectangular tubular member having slits in opposite sides thereof,.of a member carrying two nested U-shaped clips the legs of which are spaced apart and embrace the unslitted sides of the tubularmember, a pin pi votally securing the clips to the tubular nieinber,-and a sleeve upon the pin between the legs of the inner clip.

4. The combination with a substantially rectangular tubular member having slits in opposite sides thereof, of a member carry ng two nested U-shaped clips the legs of whlch are spaced apart and embrace the nnslitted sides of the tubular member, a pin pivotally securing the clips to the tubular member, a sleeve uponthe pin between the legs of the inner clip, and means for adjustably applying pressure tothe said partslongitudinally of the pin. I

5. The combination With a substantially rectangular tubular member having slits in opposite sides thereof, of a member having two pairs of spaced legs that embrace, respectivelyfthe unslitted sidesof the tubular member, a bolt pivotally securin the said legs to the tubular member, and a s eeve upon the bolt between the said pairs of legs.

6. The combination with a substantially rectangular tubular member opposite sides of-Which are slitted along their edges and conform in shape to the adjacent sides, of a member carrying two nested U'-shaped clips the legs of which are spaced apart and embrace the unslitted sides of the tubular meml.)er, a bolt pivotally securing the clips to the tubular member, and a sleeve upon the pin between the legs of the inner clip.

7; The combination with a substantially rectangular tubular member, opposite sides of \vhlch are slitted along their edges and conform in shape to the adjacent sides, of a member having two pairs of spaced legs that embrace, respectively, the unslitted sides of the tubular member, a bolt pivotally securin the said legs to the tubular member, and a s eeve upon the bolt between the said pairs of legs.

8. The combination with a member having a plurality of spaced projections, of another member carrying a plurality of nested U- shaped clips the legs of which are spaced apart and embrace the said projections, and

means for pivotally connecting the clips to.

the projections andfifor clampingthe said parts together.

In testimony whereof, I have hereunto subscribed my name this 28th day of Dec,

FRED R. KUNKEL. "Witnesses M. SCHEIBE, BIRNEY HINES.
